A systems approach for evaluating the feasibility of engineering noise control is presented. Techniques are described for analyzing punch press noise, important noise sources are identified, and the noise characteristics of selected machines are defined. A state-of- the-art demonstration of noise control is described. Results include consideration of air exhaust, machine speed, radiating area, tool geometry and workpiece material, as well as possible modifications of press stiffness, mass, and damping. Finally, fundamentals of punching and empirical equations for punching noise are given.
